• R438A (Freon™/Isceon MO99) is a HFC blend, used as a replacement for R22 in domestic, industrial and commercial air-conditioning systems

• It is also a retrofit replacement for R22 in low and medium-temperature refrigeration systems and DX chiller systems

• Available from A‑Gas wholesale partners - find your local distributor for further details

• A‑Gas product cylinders are fitted with a Residual Pressure Device (RPD) to ensure used refrigerant or any other substance cannot be reintroduced into a cylinder

• Store cylinders in a cool, dry, well-ventilated area, out of direct sunlight

• A‑Gas operates a returnable cylinder fleet - empty cylinders are to be returned to an A‑Gas wholesale partner

• For alternative or larger package sizes please contact A-Gas on 1800 002 427 or via the Contact Us form

• Substitute for R22 and R13B1

• Near azeotropic refrigerant blend containing R32 and R125

• Refrigerant must be charged from the liquid phase to ensure accurate composition

• A‑Gas refrigerant cylinders have dual port valves, making liquid offtake easier

• Non-flammable with a safety classification of A1

• Compressors must be charged with polyolester oils - contact the compressor manufacturer for more information

• Distinct higher efficiency in comparison with R22

• Not a retrofit replacement due to much higher operating pressures

• Higher pressures of this refrigerant are to be considered - especially with regards to system components
